 // - local (kFileSystemTypeLocalNative): a local file system on which files are

 // - restricted (kFileSystemTypeRestrictedLocalNative): a *read-only* local file
 //   system which can only be accessed by extensions that have full access to
 //   external file systems (i.e. extensions with fileManagerPrivate permission).
 // - drive (kFileSystemTypeDrive): a file system that provides access to Google

 // The tests cover following scenarios:
 // - Performing file system operations on external file systems from an
-//   extension with fileManagerPrivate permission (i.e. a file browser
-//   extension).
+//   app with fileManagerPrivate permission (i.e. Files.app).
 // - Performing read/write operations from file handler extensions. These
 //   extensions need a file browser extension to give them permissions to access
 //   files. This also includes file handler extensions in filesystem API.
 // - Observing directory changes from a file browser extension (using
 //   fileManagerPrivate API).
 // - Doing searches on drive file system from file browser extension (using
 //   fileManagerPrivate API).
